	 Usage Note:
	 -----------
	 Do not use both ajaxSubmit and ajaxForm on the same form.  These
	 functions are intended to be exclusive.  Use ajaxSubmit if you want
	 to bind your own submit handler to the form.  For example,

	 $(document).ready(function() {
	 $('#myForm').bind('submit', function(e) {
	 e.preventDefault(); // <-- important
	 $(this).ajaxSubmit({
	 target: '#output'
	 });
	 });
	 });

	 Use ajaxForm when you want the plugin to manage all the event binding
	 for you.  For example,

	 $(document).ready(function() {
	 $('#myForm').ajaxForm({
	 target: '#output'
	 });
	 });

	 When using ajaxForm, the ajaxSubmit function will be invoked for you
	 at the appropriate time.

	 *  is used to submit the form).
	 * 2. This method will include the submit element's name/value data (for the element that was
	 *  used to submit the form).
	 * 3. This method binds the submit() method to the form for you.
